What are the current business rates thresholds for Cornwall holiday lets?

From 1 April 2025: 252 days available AND 105 days actually let in the previous 12 months. Both tests must be met. The thresholds increased from the April 2023 levels of 140 days available / 70 days let. The property must also have been used commercially with a view to profit (not just made available to friends or family at discount).

How much could business rates save me vs Council Tax?

Typically £2,000–£4,500 per year on a 1-3 bed Cornwall cottage. If your Rateable Value is under £12,000 (most modest holiday lets), Small Business Rate Relief gives 100% relief — zero bill. Council Tax for the same property in Cornwall would be £1,800–£2,400/year base, doubled by the 100% second-home premium. The saving on a Band C cottage is roughly £3,600/year.

How do I apply for business rates on my Cornwall holiday let?

Apply directly to the Valuation Office Agency (VOA) at gov.uk — not Cornwall Council. The VOA assigns your Rateable Value. Cornwall Council then issues the bill. After getting your RV, apply to Cornwall Council for Small Business Rate Relief — it's not automatic. Allow 8-12 weeks for VOA processing during peak periods.

What evidence do I need to prove I hit the threshold?

Booking calendar showing 105+ let days, OTA statements (Airbnb, Booking.com, Vrbo) or agency remittance reports proving the bookings happened, advertising evidence showing the property was offered for 252+ days, and a record of any owner-use days (which don't count). Keep these for at least 6 years — VOA and Cornwall Council can audit retrospectively. Saving everything in cloud storage is a sensible practice.

Does Cornwall Council exempt any second homes from the premium?

Yes — a few narrow exemptions apply. Properties subject to a planning condition that restricts occupancy (e.g., must be used as holiday accommodation only, or cannot be lived in continuously for more than 28 days) are typically exempt. Properties undergoing major renovation in some circumstances. Annexes to a main home that are part of the same household. Most ordinary second homes and holiday lets that fail the business-rates threshold do not qualify for exemption.

What if I'm just over the threshold one year and under the next?

The VOA reassesses regularly and a property reverting to under-threshold can be moved back to Council Tax. There's typically a lag — you don't get switched immediately on a single bad year. But consistent under-letting over 2-3 years will trigger reassessment. Aim to be comfortably above 105 days (target 130-150+) to leave a buffer for occupancy variation.

Holiday Let Business Rates vs Council Tax in Cornwall (2026)

The single biggest avoidable cost on a Cornwall holiday let is paying Council Tax when you should be paying business rates. Properly qualifying for business rates (with Small Business Rate Relief) can mean a £0 annual bill on a property that would otherwise pay £3,000-£5,000+ Council Tax — and Cornwall's recent 100% second-home premium makes the maths sharper still. Here's the 2026 picture.

The two regimes in brief

If a property is your main residence, you pay Council Tax. If it's a holiday let that meets the qualifying tests, you pay business rates instead. Holiday lets that don't meet the tests are treated as second homes — which means Council Tax, with Cornwall Council's 100% premium on top.

	Business Rates (qualified)	Council Tax (failed)
Threshold	252+ days available, 105+ days let (from April 2025)	Falling short of either
Small relief	100% SBRR if Rateable Value (RV) under £12,000	None for holiday lets
Cornwall premium	N/A	100% second-home premium (200% Council Tax total)
Typical 2-bed cottage	£0–£2,500/year	£3,200–£4,800/year (Bands C-D, with premium)

The April 2025 threshold change

Before April 2023, a holiday let could qualify for business rates with essentially no occupancy proof — owners self-declared availability. The April 2023 rules changed that, requiring properties to be available for letting 140+ days AND actually let for 70+ days per 12-month period.

From 1 April 2025, these thresholds were raised significantly: 252 days available AND 105 days actually let. gov.uk guidance sets out the new tests and the evidence required.

The change is significant because it pushes genuinely marginal holiday lets into Council Tax. A property only let for 60-90 days per year — common for second-home-cum-holiday-let arrangements — used to qualify under the old 70-day threshold but now doesn't. Plenty of Cornwall properties fall in this gap and have been recently reclassified.

The Cornwall 100% second-home premium

Cornwall Council, using powers granted by the Levelling Up and Regeneration Act 2023, applied a 100% Council Tax premium on second homes from 1 April 2025. Owners of furnished properties not used as their main residence now pay double the standard Council Tax — and this stacks on top of failing the business-rates threshold. Cornwall Council second-homes page.

Implementation revenue: Cornwall reported around £24.7 million in additional Council Tax revenue from the premium in the first year (March 2025–March 2026), from approximately 10,740 properties classed as second homes.

Worked example: 2-bed cottage in Newquay

Take a typical 2-bed cottage in Newquay (Council Tax Band C; Cornwall Band C 2025–2026 standard charge approximately £1,800/year):

Scenario A: Qualifies for business rates (260 days available, 120 days let)

Rateable Value (assumed): £10,500
SBRR threshold (£12,000): qualifies for full 100% relief
Annual bill: £0

Scenario B: Falls short (260 days available, 80 days let — fails the 105 threshold)

Reverts to Council Tax Band C: £1,800/year
Plus 100% second-home premium: +£1,800/year
Annual bill: £3,600/year

That's a £3,600/year difference on the same property — driven entirely by whether you let it for 25 more nights. For most Cornwall holiday lets, the case for genuinely targeting (and hitting) the 105-day threshold is overwhelming.

Small Business Rate Relief — the killer benefit

Properties that qualify for business rates often qualify for further relief via the Small Business Rate Relief (SBRR) scheme. The bands (2025–2026):

RV under £12,000: 100% relief (zero bill)
RV £12,000 to £15,000: tapered relief (linear from 100% to 0%)
RV over £15,000: no SBRR (full bill applies, currently 49.9p in the £ for small businesses)

Most modest Cornwall holiday lets (1-3 bed cottages, small apartments) have Rateable Values comfortably under £12,000 — meaning fully qualifying for business rates wipes the bill entirely. Larger 4-5 bed properties or premium-postcode harbour-side cottages may have RVs in the £12,000-£20,000 range, where SBRR is tapered or absent.

The gov.uk business rates calculator shows your bill given an RV. Your RV is on the Valuation Office Agency (VOA) website (check your business rates valuation).

How to qualify (and prove it)

Practical steps to qualify for business rates from April 2025:

Actually make the property available for 252+ days/year with realistic, market-rate advertising. "Available" means listed on at least one credible OTA or your own direct booking website, at rates the market will accept. HMRC and the VOA check the listing data, not just your word.
Achieve genuine bookings for 105+ days/year. Family use, friend stays, owner-occupation, and free/discounted nights don't count. Cancellations and unfulfilled bookings don't count either.
Keep an evidence pack: annual booking calendar, OTA statements, agency remittance reports, owner-use diary, advertised rate schedule. Cornwall Council and the VOA can request these.
Apply to the VOA to be rated (not Cornwall Council — that's billing only). Your property gets a Rateable Value, and from then on you're in the business-rates system.
Apply to Cornwall Council for Small Business Rate Relief once you have an RV. The relief isn't automatic — you have to apply. Once approved, it usually rolls forward year to year without re-application unless your circumstances change.

Hitting 105 let days — how achievable?

For Cornwall properties, 105 days = roughly 15 weeks of actual letting. The 2025 Cornwall average occupancy of 61% on a year-round-available property would deliver around 222 let days — well above the threshold. Properties failing the threshold are almost always under-letting, not over-letting:

Properties marketed only in summer (May-September only) typically achieve 80–120 let days — borderline
Properties marketed all year (with appropriate winter pricing and off-season targeting) typically achieve 150–250 let days — comfortably above threshold
Properties used 8+ weeks/year by the owner personally start running out of available days fast

If you're a Cornwall holiday-let owner currently failing the 105-day threshold, the questions to ask:

Is the property properly marketed multi-channel (Airbnb + Booking.com + Vrbo + direct), not just Airbnb?
Is the off-season pricing aggressive enough to actually fill nights (often £40-£60/night for shoulder season is what the market clears at)?
Is there a hot tub / log burner / Wi-Fi setup that supports winter and shoulder bookings, not just summer?
Are you blocking out too many owner-use weeks?

Fixing two or three of those usually pushes a marginal property comfortably over the 105-day threshold.

What if you can't hit the threshold?

If your Cornwall property genuinely can't trade 105+ days (because of property restrictions, lifestyle constraints, or limited market), the maths gets harsh. You're paying:

Standard Cornwall Council Tax (Band varies; typical 2-bed £1,600-£2,000/year)
Plus 100% second-home premium (doubles it)
Plus, if you have a mortgage, the post-FHL restricted interest relief

For a Band C Cornwall property, that's roughly £3,600/year just in Council Tax before any other costs. Combined with reduced FHL tax efficiency, marginal lets become genuinely uneconomic.

Options if you genuinely can't hit the threshold:

Move to a year-round assured-shorthold tenancy and exit holiday letting
Sell the property (mindful of the post-2025 24% residential CGT — see our FHL changes guide)
Move into the property as your main residence (eliminating both Council Tax premium and any holiday-let-specific costs)

The future direction

Cornwall Council's position has been firm: second-home and under-let-holiday-let properties contribute to the housing crisis, and the premium is intended to push owners toward either active letting or selling. The April 2025 threshold change reinforces this. Expect the political direction to continue rather than reverse — plan as if the new threshold is permanent.

Bottom line

Hitting the 105-day business-rates threshold is the single most-valuable annual tax decision a Cornwall holiday let owner makes — typically £2,000-£4,500/year of saving on a small property. If your current property is borderline, fixing the marketing and pricing strategy usually pushes you over the line. For properties that genuinely can't trade the days, the maths now strongly suggests exit (sell, or convert to long-let).

For Cornwall properties trading at the borderline, a professional management agency or letting-only service can usually push occupancy past the threshold — and the SBRR saving alone often pays the agency commission several times over.
